Liverpool's biggest concern ahead of this tricky opening assignment is the fitness of forward Firmino, who left the field early against Tottenham Hotspur at the weekend because of a nasty eye injury.

Speaking on the eve of the PSG showdown, Klopp was unable to confirm whether Firmino will be cleared in time to feature, but he will give the Brazilian every possibility.

Fringe players Origi and Solanke are both carrying knocks, meaning that Daniel Sturridge is the obvious candidate to replace Firmino in the forward line if worse comes to worst, alongside Mohamed Salah and Sadio Mane.
